Question

Does the Prototype Javascript library have a selector that’s equivalent to jQuery’s :contains()? If not, what would what be “The Prototype Way” to selector/filter-down a list of elements that contains a particular string.

For example, using the following

$$('#some_div dd a')

I may get back an array of 50 or so links. I only want the links that contain the work ‘home’. In jQuery I’d do this

jQuery("#some_div dd a:contains('home')");

Is it possible to do something similar using Prototype? If not, is there an elegant way to filter out the array of 50 elements that gets returned.

Answer 1

The best (non-Sizzle) answer I’ve been able to find so is to filter things out with the findAll method.

$$(selector).findAll(function(e){ return e.innerHTML.indexOf(label) != -1;})
